Sure. Hey, Crispin, it's Mark. So, you can look at, I think, good place to look is Slide 8. So, Slide 8, you can see here right, so we shrunk the portfolio, we shrunk the mortgage, we shrunk sort of our mortgage exposure, sort of consistent with change in our equity base. We referenced that as we went from 6.9 to 6.8, so roughly kept the mortgage exposure the same. So, smaller portfolio because of the drop in equity, but you can see that we increased total amount of duration of our hedges, right? And that was a function of rates going up and mortgages extending. So, now a lot of the mortgage market now, if you talk about Fannie 2.5s and Fannie 2s, they're kind of already fully extended and you've been seeing a rally, right. The , you know got to about 350 at some time in the second quarter. Then it's rallied back to 275 and you slowed off a little bit from there, but those fully extended securities now don't have a lot of difference in duration as a function of, sort of interest rates moving around where they are right now because if the regular mortgage rate is 5%, and maybe it got up to a high of for someone sitting there with the Fannie 2, maybe they have a , they're not getting in the money or out of the money. So, their prepayment expectations are now driven primarily by turnover. So that's cash out refinancings, it's people moving. So, a chunk of the portfolio doesn't really have a lot of negative convexity now and by that it means it doesn't require a lot of delta hedging now for changes in rates. We had those delta hedging needs when you know Fannie 2s were over par and then they go down to 84, so, then in that whole sort of passed down that their duration extended a lot. So, now I'd say where we see most of the delta hedging needs has to do with some of the higher coupons, primarily Fannie 4.5, 5 and a little bit 5.5.
